Standard Water Polo Ball Characteristics
Ball weight is 400-450 grams (14-16 ounces) and inflated to 90-97 kPa (kilopascals) gauge pressure (13-14 psi) for men and 83-90 kPa (12-13 psi) for women. Water polo balls come in two main sizes: a size 5 (68-71 cm in circumference), intended for use by men, and a size 4 (65-67 cm in circumference), intended for women. Smaller balls are sometimes used by juniors for "mini-polo," though these miniature balls do not typically come in standard sizes and are often coloured green.
